IMPROVEMENT IN PAGING BOUND BOOKS.

Spcciticatlon forming part of Letters Patent No. SLGS, dated March F20,1553, ant-edated September 29, 1852.

To @ZZ wtcnt it' may concern:

Be it known that I, JOHN McADaMs, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and useful Method ofNumbering the Pages of Books, and I do hereby declare that the followingis a full, clear, and exact description ofthe construction and mode ofoperation of the machine for performing the same, taken in connectionwith the accompanying drawings, making part of: this specification, inwhicl Figure 1 is a front elevation. Fig. 2 is a side elevation. Fig. 8is a front elevation of that part ofthe machine which performs the printing, drawn to a larger scale; and Fig. et is a vertical transversesection of the same, tak en through theuniddle of the type-chains.

The subject-matter of my invention relates,

` principally, to a new method of printing the numbers upon the pages ofblank books after they are bound; and it consists in applying the typesso as to print simultaneously upon opposite sides of the alternateleaves, and thus complete the work as it progresses, and in a new mannerof constructing and combining the several parts of the machine, so as toeffect the printing of the odd and even numbers of the alternate leavesof the bound book by one movement ol' the treadle worked by the foot oft-he operator.

The same letters of reference in the descrip tion indicate like parts inall the figures.

A is the frame ot' the machine, upon which the several parts aremounted, as shown.

B is the table upon which the book is laid,t

when paged, as shown in Fig. l.

O C are the upper and lower jaws of the printing apparatus. The upperjaw, O, is made movable, being hinged to the lower one at c. The lower jaw, C, is fixed, and is secured to the bracket B, which projects backfrom one of the frames of the machine, as shown. These jaws are made ofthe form shown, so as to receive the shafts D D', around each of whichone of the type-chains E Il, respectively, pass. That part ofthe shaftwhich is embraced by the type-chain is made square, and of a diameterequal to the width of the several links of the chain, so that itembraces the shaft firmly and is held steady when the impression isgiven, and is carried forward when the shaft is turned. The shafts D Dhang nearv the outer extremity of the jaws, so that when the upper jawis vibrated the shaft D moves through considerable distance. Near oneend of cach shaft is a square part, c, upon which the spring a bears, bywhich the shaft is held in the proper position to present the typestruly to give the impression. Z) b are ratehets upon the shafts D D, offour teeth each, corresponding tothe four sides of the shafts. They areworked by pawls b and levers d, which turn upon the shafts as fulcra, asis shown more distinctly in Fig. 4. The outer ends of the levers d areeach attached to one end of the links e, the other end of which isattached tothe opposite jaw of the machine, so that when the jaws areopened and closed it produces a quarter-revolution of each of the shaftsin a perfectly obvious manner. I

The type-chains E E are made of metallic plates, hinged together in theform of an endless band, as shown, upon which the stereotyped liguresare soldered. The upper chain, E', is furnished with the even numbers, 24 6, Src., in regular succession, and the lower one, E, with the oddones, l 3 5, 5cc., in the same manner. They are made of sufficientlength to receive a series of numbers snflicient to page any ordinarybook. The chains are supported when the printing takes place and arecarried forward between the impressions by the shafts D D', as alreadydescribed. They are supported at the other extremity upon the pulleys g,around which they pass.

F is a plate ef metal, which is hinged at one end at c, called thetongue or separator,77

' which is placed between the two leaves of the book which are beingprinted and serves as a platen to each chain of types. f is a bridlewhich is attached to one side of the tongue, which is made to serve thedouble purpose of preventing the jaws from opening too wide, and also ofbringing the tongue to an intermediate position when the jaws areopened, as shown in Fig. Lt, to permit the leaves to be readily insertedabove and below it.

G is an endless belt, made ot' mole-skin or ribbon, called thesniutbelt, which passes around the outer end of the tongue and alongeach side of it, as shown, and serves as a tympan-sheet to each seriesof types. `It is made to move along a short distance at each impression,being carried by the pulleys g over 2 v aces which it passes, which alsosustain the typechains and are carried by them as before described. Forthis reason the pulleys g are made with two scores so as to receiveboth.4 The smut-beltis further guided for convenience by the pulleys g.

I-I is a forked rod, which is attached at its upper end to the upperjaw, C', and leads down to the treadlc I, by which the machine isworked.

J is a counterpoise upon the treadle to raise it when relieved by thefoot.

K is a standard, which is fastened to the floor at a distance from themachine according to the length of the type-chains, upon which arearranged the several pulley-stands, as shown, for supporting thetype-chains and smut-belt.

L in Fig. l represents a section of a book in the position in which 'itis placed when it is paged. The two leaves extended horizontally showtheir position when they are printed. Those that are bent upI show theirposition before they are printed, and those which hang down theirposition afterward.

The operation ofthe machine is as follows Before commencing to page abook both the type-chains are inked with a hand-inking roller, such asis used by printers, and the chains are carried along until the figure 2of the upper chain andthe number next preceding, 1, ofthe lower chainare brought opposite each other, ready for the impression. The book isthen laid upon the table B with the covers turned back, as shown in Fig.l. It is then placed in such a position that when the leaves areextended naturally they will be in proper relation to the types whichare to give the impression, so as to print the number in the right placeon the page. The operator sitting in front4 of the machine then leansthe right arm upon the bock to hold it, and seizes the whole mass ofleaves with the right hand by the corner next the printing apparatus,and bends them up out of the way,

. as shown in Fig. 1. The first leafto be paged is then detached by theleft hand and placed between the tongue and copper chain, the leaf beingextended to its natural position, as shown by the horizontal leaves inFig. 1. The impression is then given by the foot, which prints upon theupper side of theleaf the number 2. The foot is then raised, which opensthe jaws, and by the operation of the ratchets and their appendages,before described, each of the shafts D is turned one-fourth of arevolution, which brings the next number in each chain to the properposition to be printed.

The leaf that was before printed is then passed below the tongue toreceive an impression from the lower chain, and the next leaf isdetached from the'mass in the right hand and inserted in its place. Theimpression is again given, which prints the number 1 upon the under sideof the first leaf and the number 4 upon the upper side of the second.The operation of discharging the lower leaf, passing the upper onevbelow the tongue, and inserting a fresh leaf' above it is repeated ateach impression until the book is finished. Thus an accurate registeringof the printing with any required margin is produced by simply holdingthe book fixed and bringing the leaves to be printed to their naturalposition, the others being bent out 0f the way above and below them, asshown.

The principles of my invention are susceptible of considerable varietyin construction and application. Thus, instead of figures, letters orwords may be used, if required, and a chain of types may be used in amachine of this description having the address of' persons thereon forthe purpose of' printing the address of' subscribers upon the envelopesof newspapers and for other similar purposes; or but one chain maybeused with all the numbers thereon in consecutive order, as l 2 3, &c.,for the purpose of paging letter-copying books when the number isprinted only on one side of the leaf 5 and, so, instead of the endlesssmut-beltof mole-skin above mentioned a fillet of paper may be used, notmade endless, but unrolled from one coil onto another, and I have soused it with advantage; or the fillet may be used with the mole-skinupon the outside of it, which will give a more elastic impression. lVhenthe machine is used constantly, the use of the paper fillet isnecessary; but when used only occasionally, it is not necessary.

New, I do not claim the use of type-chains for paging books, as theyhave already been secured to me by Letters Patent granted August 12,1851; but

1V hat I do claim as new, and desire to secure by Letters Patent. is-

The employment of' the square rotating shaft D as a bed for the oddnumbers and the shaft Das a bed for the even numbers of the types, incombination with the tongue F as a platen to both sets of types, thesame being operated by the treadle, ratchets, and pawls, so as to enablethe operator to printthe odd and even numbers of the alternate pages ofa bound book by a single movement ot' the ireadle, as above described.
